JACK....If you are fortunate enough to own & play a TECHNICS KB....with an automatic rhythm & 1 finger or basic chord setting....the keyboard can help you learn the different chording sequences....
There is lots of music that has the chord icon above the treble cleff that is easy to see as you look at the notes....
I forgot that you are an ear player...
Find a book in a music store...teach yourself all the chords....That works!
I play by reading...with automatic rhythms & using the "basic" fingering chords...Frequently I am able to just make the chord changes without really knowing what I am doing...I recognise a change is needed & somehow my fingers go to the right one most of the time....
Persistence pays!
Happy Playing! ELIZABETH
